SPECIFICATION forming part of Letters Patent No. 326,643,6ated September22, 1885. Application filed October-16, 1884. (No model.)

To all whom, it may concern.-

Be it known that I, VVILLIAM S. HALSEY, of Oakland, county of Alameda,and State of California, have invented an Improvement in Mowers; and Ihereby declare the fOllOwing to be a full, clear, and exact descriptionthereof.

My invention relates to that class of agricultural implements known asmowers, in which the sickle or knife is driven by power derived from thewheels and transmitted through suitable shafts and gears; and myinvention consists in a sleeve loosely mounted on the counter-shaftwhich carries the bevel gear, said sleeve having at one end a collaragainst which the hub of said gear bears, and at its other end aset-screw which is seated in the yoke mounted on the counter-shaft, andwhich carries the shaft which bears the pinion engaging with the gear,as I shall hereinafter fully explain.

The object of my invention will be set forth how strong the thrust maybe, it but throws in the course of the following description.

Referring to the accompanying drawings, Figure 1 is a rear elevation ofa mowing-matchine, showing my invention, the side frame of the machinecarrying the sickle mechanism being omitted. Fig. 2 is a plan showingthe counter-shaft, shaft D, gear, pinion, and yoke, and the applicationthereto of my invention. Fig. 3 is a longitudinal section of the sleeveF. A are the wheels, from one of which,in the usual manner, by means ofthe internal gear and a pinion, power is transmitted to drive thecounter-shaft B, mounted in hangers a at the rear of the machine. 0 isthe usual yoke, through the arms of which the shaft B passes. This yokecarries the shaft D, Fig. 2, which extends forward to drive the sickle.Upon shaft B is a bevel-gear, b, which meshes with a bevelpinion, d, onshaft D. E is the clutch by which the gear I) is thrown into or out ofconnection with shaft B. These parts are arranged and operate in awell-known manner, and constitute sufficient of the machine to show theapplication of my invention.

Heretofore it has been difficult to keep the gear b and pinion d inconstant and perfect engagement, as the thrust on the counter-shaft hasa tendency to move the gear I) back from the pinion. It has beenattempted to obviate this difficulty by means of collars on the shaftbearing against the hangers; but these means have proven unsatisfactoryand do not effect a perfect result. It is the object of my invention tohold the gear and pinion in constant engagement.

Upon shaft B is loosely mounted a sleeve,F, one end of which is enlargedto, or is provided with, a collar, f, as shown in Fig. 3, against whichthe hub b of gear I) bears. The other end of the sleeve has a lug orcar, G, through which a set-screw, g, passes, and is seated in one armof the yoke C. It will thus be seen that when the thrust on shaft Btends to carry the gear away from the pinion, the hub of the gearbearing against the eollarfon the sleeve transfers the effect ofthethrust through said sleeve and its screw to the yoke, and as thisyoke carries the shaft D which bears the pinion d, it is obvious thatsaid pinion is thrust over also, and its engagement with the gear I) iscontinued. Therefore, no matter both gear and pinion in the samedirection and to the same distance, whereby their engagement is notbroken.

The sleeve F being loose upon the drivingshaft does not interfere withits operation,but on the contrary protects it from the grass,&c., which,when the shaft is exposed, clings to and winds around it.

The sleeve being stationary does not so collect the grass, weeds, &c. Asthe sleeve is fixed and the gear Z) rotates, there will be wear upon thecollar f on the end of the sleeve. This wear can readily be taken up byadj usting the set-screw 9.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a mowingmachine having a countershaft, B, with gear I), a shaft,D, with pinion d, and a yoke,O, mounted on the counter-shaft andcarrying shaft D, the loose sleeve F on 5 the counter-shaft, againstwhich the hub of gear I) bears, and a connection between said sleeve andthe yoke, whereby the thrust on gear I) is transferred through sleeve Fto the yoke to maintain the engagement of pinion d with said gear,substantially as herein described,

2. In a mowing-machine having a counterand carrying shaft D, the loosesleeve F on the shaft, B, with gear I), a shaft, D,with pinion d,counter-shaft having a oollar,f, on one end and a yoke, G, mounted onthe counter-shaft against which the hub of the gear 12 bears, and I 5and carrying shaft D, the loose sleeve F on a set-screw. g, at its otherend seated in the 5 the counter-shaft connected with the yoke at yoke G,substantially as and for the purpose one end and having a collar, f, onthe other herein described.
